Advances in theory: Martensite by design
نویسنده
چکیده
The depth of scientific understanding of martensitic transformations provides a strong foundation for the predictive design of materials exploiting artensitic phenomena. Recent theoretical advances supporting this capability include twoand three-dimensional applications of Landau–Ginzburg heory to martensitic nucleation, and important refinements of multiscale kinetic theory. Accurate control of transformation kinetics in ferrous lloys has provided both (a) commercial stainless maraging steels exploiting isothermal martensitic transformation in processing and (b) designed econdary-hardening martensitic steels exploiting optimized dispersed-phase transformation toughening in service. Predictive design of low-misfit oherent nanodispersion-strengthened shape memory alloys offer significant advances in actuation power density and cyclic life. 2006 Elsevier B.V. All rights reserved.

Texture Evolution in Low Carbon Steel Fabricated by Multi-directional Forging of the Martensite Starting Structuree
It has been clarified that deformation and annealing of martensite starting structure can produce ultrafine-grained structure in low carbon steel. This study aims to investigate the texture evolution and mechanical properties of samples with martensite structure deformed by two different forging processes. The martensitic steel samples were forged by plane strain compression and multi-directio...
متن کاملNonlinear Vibration Analysis of Composite Plates with SMA Wires, Considering Instantaneous Variations of the Martensite Volume Fraction
In the past few years, extensive improvements have been accomplished in reinforcing the structures through using shape memory alloys (SMAs). These materials absorb or dissipate energy through establishing a reversible hysteresis loop during a cyclic mechanical loading. This unique characteristic of the SMAs has made them appropriate for sensing, actuation, absorbing the impact energy, and vibra...
متن کاملComplete Calculation of Steel Microstructure for Strong Alloys
Strong steels also have to be tough and hence rely on fine microstructures such as bainite or martensite, produced commercially by continuous cooling transformation. Depending on the detailed requirements, the steel-design process may explicitly require other higher temperature phases to be absent in the final microstructure. Such a procedure can be made easier by the availability of a good met...
متن کاملON THE FUZZY SET THEORY AND AGGREGATION FUNCTIONS: HISTORY AND SOME RECENT ADVANCES
Several fuzzy connectives, including those proposed by Lotfi Zadeh, can be seen as linear extensions of the Boolean connectives from the scale ${0,1}$ into the scale $[0,1]$. We discuss these extensions, in particular, we focus on the dualities arising from the Boolean dualities. These dualities allow to transfer the results from some particular class of extended Boolean functions, e.g., from c...
متن کاملCritical Assessment : Martensite – Start Temperature for the γ → ε Transformation
It is increasingly important in the context of high–manganese steels of the kind that lead to twinning–induced plasticity to be able to estimate the temperature at which ε–martensite forms when austenite is cooled. We find that the thermodynamic method used in similar calculations for α martensite cannot in many cases be implemented because of apparently imprecise thermodynamic data, a conclusi...
